Coweeta site, station McDowell County, NC (FIPS 37111), study of number of farms in units of number on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Coweeta (CWT) contains number of farms measurements in number units and were aggregated to a yearly timescale.生态趋势（EcoTrends）项目由黛布拉·彼得斯博士（乔尔达纳盆地长期生态研究站（LTER），美国农业部农业研究服务局（USDA-ARS）乔尔达纳试验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站（LTER），美国农业部林务局（USDA-FS）卢奎洛试验林）于2004年创立，旨在支持长期生态数据集的收集与分析工作。 该项目为一项大型综合研究计划，致力于提升长期数据的可获取性与应用价值。目前共有约50个由州政府与联邦资助的研究站点参与并为生态趋势（EcoTrends）项目贡献数据，其中包括全部26个长期生态研究站（Long-Term Ecological Research, LTER），以及由美国农业部农业研究服务局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）与众多高校资助的站点。 生态趋势（EcoTrends）项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式Web应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究网络溯源感知综合跟踪架构（PASTA）的组成部分，正在推进的数据汇编工作将通过人工与自动两种处理方式进行更新。该网络门户由乔尔达纳LTER与LTER网络办公室合作开发运营。本项源自科韦塔（CWT）的数据集包含以若干单位计量的农场测量数据，并已按年度时间尺度进行聚合整理。
